WorksheetsCFA Density Review
Total questions: 15
Worksheet time: 8mins
The density of an object is
The mass divided by the volume D = m/v
The volume divided by the mass D = v/m
The same as its weight
The same as the size of the object
If two objects have the same volume but one has a greater mass, the one with greater mass
Has a lower density
Has a higher density
Will float
Will sink
If two objects have the same volume but one is made up of smaller and heavier atoms, the one with small heavy atoms will
Be larger than the other
Be less dense than the other
Be more dense than the other
Float
If you cut a wooden block in half, each half would have
Half the density of the original piece
Twice the density of the original piece
The same density as the original piece
No density at all
If two objects have the same mass but different volumes:
The one with the larger volume has the lower density
They must have the same density
The one with the larger volume has the higher density
The one with the larger volume is twice as dense
Density is a characteristic property of a substance. This means that the density of water
a) Changes depending on the volume
b) Stays the same regardless of the volume
c) Is greater for a greater mass of water
d) Is less for a smaller mass of water
100 milliliters of water has a mass of 100 grams. If you measured the mass of 50 milliliters of water, the mass would be
25 g
200 g
100 g
50 g
An object should float in a liquid if it is
More dense than the liquid
Less dense than the liquid
Lighter than metal
Shaped like a ball
A tiny piece of sand is very light but sinks in water. This is because
Sand is a solid
Sand is less dense than water
There is more water than sand
Sand is more dense than water
Wood floats in water. If you measured the mass of the same volume of wood and water
The water would have a greater mass
The water would have a lower mass
The mass of the wood and water would be the same
The mass of the wood and water would both be 100 grams
A candle floats in water but sinks in alcohol. This is because
The candle has less mass in alcohol
The water has less mass than the alcohol
The water is more dense than the alcohol
Water and alcohol are both liquids
Alcohol is less dense than water. If you measured the mass of the same volume of alcohol and water
The water would have a greater mass
The water would have a lower mass
The mass of the alcohol and water would be the same
The mass of the alcohol and water would cancel each other out
A carrot floats in salt water but sinks in freshwater. This is because
Salt water is more dense than freshwater
Freshwater is more dense than salt water
The carrot is more dense than salt water
A larger piece of carrot has a different density
The density of hot water
Is greater than the density of cold water
Is less than the density of cold water
The same as the density of cold water
Depends on the volume of water
The density of hot and cold water are different mainly because
The molecules in hot water move slower and are slightly closer together
The molecules in hot water are larger
The molecules in hot water move faster and are slightly further apart
The molecules in cold water move faster and are further apart
